drive unit 20 is configured to drive theroller 15 of thesecond cutting unit 13 in rotation in such a way that thefirst portion 16 of its outer surface, which is adapted to define the anvil for thecutting element 14, faces thecutting element 14 during the passage from the non-operating position to the operating position. - The
drive unit 20 is configured to set the firstunwinding roller 28 in rotation according to the movement of thecutting element 14 from the non-operating position to the operating position. - In use, the first cutting unit 7 operates uninterruptedly on the
continuous web 2 to obtain thesegments 5 by cutting thecontinuous web 2 according to the cutting length T. - In other words, in the condition where the
cutting element 14 is at the non-operating position, thecontinuous web 2 advances uninterruptedly from thefeed station 3, through the rotation of the firstunwinding roller 28 and of the secondunwinding roller 29, to the cutting station 7, through the rotation of theopposing element 8 and of thecutting member 9 about the respective axes ofrotation - If the
drive unit 20 causes thecutting element 14 to move from the non-operating position to the operating position, thecontinuous web 2 is severed across its full width, thereby defining anend 2a of thecontinuous web 2. - The
drive unit 20 coordinates the movement of the cuttingelement 14 from the non-operating position to the operating position with the stopping of the rotation of the first unwindingroller 28. - Stopping the feeding of the
continuous web 2 with theleading end 2a is determined by the number of work cycles needed for the first cutting unit 7 to stop cutting one ormore segments 5. - Once the
continuous web 2 has been severed, the first cutting unit 7 continues cutting theweb 2 until it reaches the trailingend 2b, whilst theleading end 2a of the remainingweb 2 is paused and kept on standby, ready to start being fed from thesecond cutting unit 13 to the first cutting unit 7 when thedrive unit 20 sets the first unwindingroller 28 in rotation again. - It should be noted that the
continuous web 2 that has been cut to make the segments 5 - that is to say, when it exits the cutting station 4 - iswaste 18 which may be continuous or discontinuous depending on whether thecontinuous web 2 has been cut at the first cutting unit 7. - During the pause, the
leading end 2a of thecontinuous web 2 is supported by theguide 30. - After elapse of the pause time, corresponding to the number of work cycles needed for the first cutting unit 7 to stop cutting one or
more segments 5, thedrive unit 20 starts the rotation of theroller 15 of thesecond cutting unit 13 so that itssecond portion 17 faces thecontinuous web 2. - After elapse of the pause time, corresponding to the number of work cycles needed for the first cutting unit 7 to stop cutting one or
more segments 5, thedrive unit 20 starts the rotation of the first unwindingroller 28 to feed thecontinuous web 2 from thesecond cutting unit 13 to the first cutting unit 7. -
Figure 6 schematically represents amachine 21 for makingcapsules 22, each comprising acup 23 for containing an infusion substance, preferably coffee, and afiltering element 5 located in the cup 23 (seeFigure 6 ). - The
filtering element 5 is intended to be welded to the inside of thecup 23. Themachine 21 comprises afeed line 24 for feeding thecups 23 and a device 1 for processing thecontinuous web 2. - The
machine 21 comprises a detectingdevice 25 for detecting thecup 23 along thefeed line 24. - The
drive unit 20 is configured to receive adetection signal 26 indicating the presence or absence of thecup 23 along thefeed line 24. - The
drive unit 20 is configured to issue a command to move the cuttingelement 14 from the non-operating position to the operating position if thedrive unit 20 establishes the absence of thecup 23 at thefeed station 6 for feeding thefiltering element 5. - Each time the
drive unit 20 establishes the absence of acup 23 at thefeed station 6, it issues a command to move the cuttingelement 14 from the non-operating position to the operating position to sever thecontinuous web 2 across its width and to stop feeding thecontinuous web 2 to the first cutting unit 7. - It should be noted that to resume feeding the
continuous web 2 that has been severed by the cuttingelement 14, the considerations set out above apply. - In short, after elapse of the pause time, corresponding to the number of work cycles needed for the first cutting unit 7 to stop cutting one or
more filter elements 5 and to the number ofabsent cups 23 along thefeed line 24, thedrive unit 20 starts the rotation of the first unwindingroller 28 to feed thecontinuous web 2 from thesecond cutting unit 13 to the first cutting unit 7.
